Einleitung

This guide was created to help replace the piezo pickup on a Carlo Robelli Acoustic guitar (CBW-4134CR). This guitar was converted to an acoustic-electric guitar by installing a preamp (EQ-7545R), which was found on Amazon after the original piezo pickup installed was not giving out an output signal or in other instances sounding poor in quality. The piezo pickup is connected to the guitar preamp's input and placed under the bridge saddles to pick up the strings' vibrations. A faulty pickup can lead to feedback noise, loud buzzing, or sometimes no signal after plugging in a 1/4 inch cable into the guitar's output. It is best to follow this guide by placing the guitar on a flat and level surface so that the guitar does not fall and break or so that the guitar pins do not roll off and get lost. This guide may help any guitar with a piezo pickup, but the steps may not be the same.
